I Application tiled .l'ulyl 18, 1898. Serial No. 686,249. (No model.)

To a'ZZ whom it may concern:

Be it known that I, OTTO ASCHE, a citizen of the French Republic, residing at Paris, in ,the Republic of France, have invented certain new and useful Improvements in Machines for Soldering Tin Cans, (for which applicasurfaces.,

tions have been filed in France May 17, 1898, and in Germany May 30, 1898;) and I do hereby declarol the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention comprises an mprovenlenl; on the machine described in my United States Patent No. 552,809, and has for its object to guide the cans to be soldered either over the heating and cooling,r surfaces or to guide them along in the apparatus under the-same. In 'the accompanying drawings I represent these two forms of apparatus.

Figure l is aside elevation, partly in sec tion, of a machine in which the tin cans are gliding over the heating and cooling surfaces; and'Fig. 2 is a plan view of the same. Fig.

3 shows the second form in side elevation,'

partly in section, the cans being guided in this machine below the heating and cooling Fig. 4 is a plan view. The general elements in the machine here# inafter described are the same'as in my latent No. 552,809.

1 is a vertical shaft, which can be adj usted in height by means of nuts 2 2.

3 is a long sleeve fitted 'to the shaft l and carrying the revolving plates ir tables.

Ai, 5, 6, and 7 is the driving mechanism, of

ordinary and well-known construction,

S'are the cooling-tables, and 91a re the neating-tables, provided with a tube or tubes 10, having openings so as to constitute a gasburner. The cooling-tables 8 may be simply metallic masses adapted to quickly take up ordinary temperature, and gas can be snpplied to the burner-tubes in any convenientv manner andrfrom any suitable source.

1l is a table carrying plates 12, (best shown in Figs. 3 and' 4,) the object of said plates loeing to minimize friction, as hereinafter def scribed, and to transmit heat Ain: one or the otherdirectlon.

13, Figs. 3 and 4, is n gnide serving to lift the piates' l2 and to allow them .to fail down again. I r

14 is afeble carrylng the supporting-plates 15 for the cans, pressing upon the latter either from above, as in Figs. 1 and 2, or freni below, as in Figs. 3 and 4. -K j 16 is a lcam or guide serving to raise and to lower the plates 15 by means of rods 17,'be ing guided in sleeves of tli'e table 14, and by means of rollers -18, running on the top and bottom edges of the 'guide 16.

19 islaslide or chute, upon which the soldered cans are guided by a. finger 20 and down which they slide to be received -into a basket or other receptacle. 'i

It is well known that when the cans pass in direct contact' over the hen-ted surface #L friction of quite a high degrel is established,

`duo tombe eantsndciiiaving @tendency to stick vor adhere to the heatedsurface. I obviate this inconvenience, orfrather defect, by providing the plates 12, as shown in the drawings. Said plates are hinged or otherwisc movably secured to the edge of the table 11. ln the .constructionshown in Figs. 3 and 1 the plates 12 rest 011 the .topsof the cans and are intermediate'the latter and the heat.- ed surface during the soldering operation. They thus serve to prevent any friction that would otherwise occur.- Vhile answering .this purpose, it is obvious that the plates are susceptible of 'transmitting suiiioient heat to readily 1n elt the solder.. As the cans continue around the machine the guide 13 serves to lift the plates 12, so that the cans can be readily removed upon reaching the point of discharge. p

The two, constructions'are duplicates of each other except that in Figs-1 and 2 the cans travel above the' heating and cooling surfaces, while in Figs. 3 and L tlxe.1everse arrangement is shown. Here also in Figs. 3

and 4 I employ the guide 13 to raise the plates l2, whereby the .removal of the soldered cans is facilitated. uThis `guide is omitted in the former'y construction The operation of my improved machine is easily understood. The 'cans are placed upon the plates 15 when the guide 16 has compressed the respective springs. Thereupon the guide. allows the springs 'to expand, and the can under pressure is guided kirstdonft veombilnition of :i

the nesting and then along the cooling sniiziee, so that the solder melts and binds the parte iogether in the manner described in my patent aforementioned. Thus the osns are under com pression during one quarter of a revolution while passing over or under the neming-table, und thendnring :mother quarter of arevolution of the machine they are presen led against the cooling-table, and iixnilly they are dief charged from the machine during the remaining one-half revolution in.' hand, or they are discharged suoimntiesllj. the finger Having thus described my invention, I claim as ne\v,and desire to sei-:nre by Leiters Patent of the United States, the following:

v 1. In apparatus for soldering: tin fea-ns, the combination of sframe, n osmnfay mounted on said frame, a nsrrier adapted to be guided by said ezunway, flexible can-holders on said carrier, a heating-surface, a cooling-surface and suitable. meehanisnrfor bringing the prepared can ends into Contact with said snrfsees consecutively, substantially as described.
